[Analysis Case] Predicting the magnetization distribution within a plastic magnet from measurement data.

Estimating the magnetization distribution from the numerical data of magnetic flux density obtained through the forward problem! Introducing an analysis case of the inverse problem.

The analysis of the magnetic field created by magnets and coils is referred to as a forward problem. On the other hand, the problem of determining magnetization or current from the magnetic field distribution is called an inverse problem. In this case, we will introduce an example (inverse problem) where we estimate the magnetization inside a magnet from numerical data of the magnetic flux density on the surface of a plastic magnet and analyze the magnetic flux density created by that magnetization. For convenience, we will estimate the magnetization from the magnetic flux density obtained through the forward problem and calculate the magnetic flux density at a different location. Since we will use the results of the forward problem, we can compare the results of the forward and inverse problem analyses to evaluate the validity of the inverse problem's analytical function. 【Case Overview】 ■ Software Used: PHOTO-MAGTZ ■ Analysis Results - The magnetic flux density at a position 1mm away from the surface of the magnet is generally consistent between the forward and inverse problems. - There are multiple magnetization distributions that indicate the same magnetic flux density. *For more details, please refer to the PDF document or feel free to contact us.
